FRED R KUNKEL, OF WILKINSBURG, PENNSYLVANIA. ASSIGNOR TO WESTINGHOUSE ELEC- TRIO dc MANUFACTURING COMPANY, A CORPORATION OF PENNSYLVANIA COIL-WINDING MACHINE.

Be it known that I, FRED R. KUNKEL, a

citizen of the United States, and a resident of WVilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Coilinding Machines, of which the following is a specification. My invention relates to means for facilitating the winding of longitudinally slotted, c 'lindrical cores for dynamo electrical niac inery and has special reference to the winding of two-pole armature-cores that are provided with partially closed slots.

The object of my inventionis to provide means for rotatably mounting and winding cylindrical armature cores that shall be simple and durable in construction and easy of application and that shall effectually guide the winding conductor into a pair of predetermined slots.

By the use of my invention, the winding of armatures having partially closed slots is materially facilitated, since provision is tation and smce guide flanges are arranged to guide the conductor into the proper slots. My invent-ion is illustrated in the accompanying drawings, in which Figure 1. is an elevation of a winding jig constructed in accordance therewith; and Fig. 2 is a plan View, the jig being shown partially in section to disclose an armature core in position.

Referring to the drawings, a cylindrical core 1, which is provided with a shaft 2 and has a plurality of partially closed slots 3, 4, 5, 6, 7,8,9,10,11, 12, 13 and 14, is rotatably mounted in and supported by a jig that comprises a head stock 15 which may enage a live center on a lathe or similar driving machine, a plurality of flanged guide plates 16 and 17 and a tail stock 18 which may engage the bed-plate of a lathe or be The flanged guide plate 16 is supportedl from, and is a part of, the head stock or hub 1 15, which also supports a plurality of bearing arms 19 and 20, that en age the armature g shaft 2, thereby rotatab l su )porting the armature so that it may be easi y re-set after The arm 20 is detachable from the head i Specification of Letters Patent.

stock 15 so that a core may be readily removed when wound and be replaced by another similar unwound armature core, while both arms 19 and 20 may be respectively provided with closed bearings 21 and 22, the axes of which are in alinement.

The approximately semi-cylindrical flange plate or cap 17 is rigidly attached to a shaft or spindle 23 which is mounted in a bearing 24 in the tail stock 18 and is forced against the core by a sprin 24, the end play of the shaft being limited by a pin 25, which is held in en agement with any one of a plurality of annular grooves 26 and 27 in the shaft 23 by a spring 28. I

he guide plates 16 and 17 together form a substantially closed hollow cylinder but are separated slightly and their edge flanges diverge outwardly, so that two slots 29 and 30 'are formed between the two, in the same vertical plane and are so arranged that when the armature is in position they lead directly into a couple of slots; such, for example, as the slots 3 and 8.

The armature core is prevented from rotation on its axis during the winding process by a pin 31 which is mounted invtlie body of the guide plate 16 and is held in engagement with one of the core slots by a s ring 32.

The bearing arm '20 is hell in position when the armature 1 is in place by any convenient means such as a hinge-bolt 33, which is attached to the head stock 15 and engages a slot 34 in the detachable portion of-the arm, and a thumb-nut 35.

After one end of a core shaft has been placed 'in the bearing 21, the bearing 22 is slipped over the opposite end and clamped in p ace. Then pin 31 is moved into engagement with one of the armature slots and the flanged plate 17 is permitted to engage the surface of the core, the center line of the tail stock bearing being coincident with that of the head stock.

An insulated conductor may now be fitted into the slots 29 and 30 as the guide plates and the armature core are rotated together. When a sufficient number of turns for a. single coil has been completed, the armature is rotated until the pin 31 engages another slot. This process is continued until the winding is complete.

It is usually found desirable to successively wind coils which are on opposite sides substantia include within its scope any other arrange- .terially from the ment or structure which does not depart masults attained.

I claim as my invention: 1. The combination with a rotatable member comprising two bearings, the axes of which are in alinement and are perpendicular to the axis of rotation of said-member, of two segmental guide plates, one of which is a part of said member, while the other is rotatably mounted upon a separate base.

2. The combination with a rotatable driving member that comprises two bearings, the axes of which are in alinement and are substantially perpendicular to the axis of rotation of said member, and a semi-cylindrical late, of a second complementary plate that is rotatably' mounted on a separate base, both of said rotatable plates'having a common axis of rotation.

3. A rotatable Winding device for slotted armature cores comprising a plurality of shaft bearings, the common axis of which is perpendicular to the axis of rotation of said device,- means for guiding a conductor into a predetermined pair of core slots assaid core is rotated, and means for engaging any one of the core slots-to lockthe core in the winding device. r

4. A rotatablewinding device for longitudinally slotted cylindrical cores comprising a plurality of bearings, the common axis of which is perpendicularto the axis of rotation ..of said device, means for guiding a conductor into a predetermined pair of core slots as said core is rotated, and a locking pin that engages a core slot to prevent the core from rotating on its axis.

5. A rotatable winding device for slotted I ssaazi-e purpose set iorthor the rearrnature cores comprising a fixed shaftbearing and a detachable shaft-bearing ha"- mg a common axis which is perpendicular to the axis of rotation of said device, means for guiding a conductor into a predetermined pan of core slots as 'sald core is rotated, and a locking device that engages one of the core slots.

6. A rotatable winding device for slotted armature cores comprising a fixed sh aftbearing and a detachable shaft-bearing having a common axis which is perpendicular,to the axis of rotation of said device, means for guiding a conductor into a predetermined armature cores comprising a plurality of 6 5 shaft-bearings, the common axis of which is perpendicular to the axis of rotation of said device, and means for guiding a conductor into a predetermined pair of core slots as said co're is rotated that comprises a pair of com-- plementary and substantially semi cylindrical caps held adjacent'to but out of engagement with the core and having diverging flanges. a

8. A rotatable winding armature cores comprising a plurality, of

shaft-bearings,-the common axis of which is perpendicular to the axis of rotation of saiddevice, means for gmdmg a conductor into a predetermined pair of core slots as said core 80 is rotated that comprises a pair of complementary and substantially semi-cylindrical lates having diverging flanges, and means or engaging a core slot to prevent the core from rotating on its axis.
